      • 칸트의 歷史哲學에 關한 一考

        韓端錫 全北大學校 1982 論文集 Vol.24 No.-

        The purpose of philosophy of history what Kant means is rather explanation concerning significance of life and basic structure for human history than that of cognitively fundamental operation for science of history. The subject-matter to be described here-in is first of historic aim in nature, secondly of history for human freedom and thirdly of order of history in aimfulness(zweckmuessigkeit). The meaning of history in Kantian sence consist of interstructures which have been worked co-determinedly between deontological necessity and practical freedom of human nature while working much for BECOMING(WERDEN) for ultimate aim, demanded by presumed origin. Furthermore, noumenal nature behind the hidden aim is understandably intending for its ultimate aim, mediated by self-conscious activity whose structure is all-purposeful with natural, cultural and moral quality working combinded.

      • 칸트에 있어서의 物自體와 自由

        韓端錫 漢陽大學校 哲學會 1989 哲學論集 Vol.- No.1

        「나는 칸트를 연구하면서, 이 의념이 나를 적지않게 포이 시켰음을 고백하지 않을수 없다. 그 때문에 나는 오랜 세월동안 계속해서 『순수이성비판』을 되풀이하여 처음부터 읽지 않을수 없었다. 왜냐하면, 나는 물자체를 전제하지 않고서는 그 체계속에 머물러 있을 수 없다는 데에 대하여 언제나 혼란되어졌기 때문이다.」라는 야코비의 말을 인용할 것도 없이, 칸트의 물자체의 개념은 극히 문제가 많은 개념이다. 반델반드도 물자체의 개념을 「칸트 인식론의 정점(Ho¨hepunkt)」이라고 부르고 있으며, 또 「물자체설과 비판주의의 체질및 핵심이 상호결부된 것이라고 생각할 수 있는가 하는 것은 단순한 역사적 해석의 한 문제일 뿐만 아니라, 또한 동시에 비판주의에 있어서는 사활문제이다」라고 논하고 있다. 하르트만도, 「칸트 학자의 괴로움의 전형적인 것은 옛날부터 물자체이었다.」라고 쓰고 있다.

      • Color Measure in the Fiction of Mo Yan’s Red Sorghum

        Han Dan,Hu Ming Hai 한국색채학회 2017 AIC 2017 Jeju Vol.2017 No.10

        Famous writers` novels are often made into movies or TV drama, the audience of these mass media works and popular art is the masses, need to be recognized by the public. We propose a way to convert the virtual colors description in the novel into the actual application colors. In the experiment, evaluate the color words in the novel by the Munsell color sample. First of all, We choose some color words in the red sorghum, then, We invited 100 experimenter for each color words to choose what they think appropriate color samples from Monsell color card and record the three-dimensional numbers of these colors H V / C. to statistical who is the most times be selected color samples. Record the most be selected color samples and the average. The experimental results is systematically recommended the color range that by the public recognized and properly embodies this novel’s color words, to avoid the color of the novel in the film and TV drama in the wrong reproduction, eliminate the discontent of the public and Receive disorder.

        GaN nanorods gas sensor for highly sensitive n-butanol detection at room temperature

        Shuai Han,Yongming Fu,Donghui Li,Dan Han,Qinjun Sun 대한금속·재료학회 2023 ELECTRONIC MATERIALS LETTERS Vol.19 No.3

        Safe and effi cient detection of hazardous n-butanol gas is very great signifi cance to the health of workers and researchers inchemical environments. In this work, we successfully developed a GaN gas sensor by a simple solvothermal method and alow-temperature nitridation process. Material characterization results show that one-dimensional nanorods structures wereobtained and the products presented a superior growth orientation along with (101) plane. The gas sensing test results showthat the sensor exhibits excellent responsivity, repeatability, and selectivity to n-butanol at room temperature. The responseand recovery time of the sensor to 200 ppm n-butanol gas was 45 s/34 s. Gas adsorption model and electron depletion layertheory were established to understand the n-butanol sensing mechanism. This work provides the possibility for its realapplication in n-butanol detection with safe and effi cient at room temperature.

      • An Optimal Combined SVM Model for Short-term Wind Speed Forecasting

        Bai, Dan-Dan,He, Jing-Han,Tian, Wen-Qi,Wang, Xiaojun,Tony, Yip 대한전기학회 2014 The Journal of International Council on Electrical Vol.4 No.4

        A high precise wind speed forecasting method is one of current wind power research hotspots. This paper presented a combined wind speed forecasting model based on support vector machine (SVM) optimized by particle swarm optimization (PSO) using historical data of wind speed at the site. The model took the results of back propagation neural network (BPNN), radial basis function neural network (RBFNN), genetic neural network (GNN) and wavelet neural network (WNN) as the inputs, and adopted the actual wind speed as the output. Meanwhile, particle swarm optimization was used to optimize model parameters. Apply this model in hourly prediction of wind speed using historical data from a wind farm in Shanxi Province. It is observed that its prediction accuracy was not only higher than that of any of its single network but higher than traditional linear combined forecasting model and neural network combined forecasting model.

        김성단(Sung-Dan Kim),김복순(Bog-Soon Kim),박성규(Seoung-Gyu Park),김미선(Mi-Sun Kim),조태희(Tae-Hee Cho),한창호(Chang-Ho Han),조한빈(Han-Bin Jo),최병현(Byung-Hyun Choi) 한국식품과학회 2007 한국식품과학회지 Vol.39 No.2

        서울지역에 유통되고 있는 국내산 및 수입산 건조농산물 58건을 대상으로 다성분 등시분석방법에 따라 GC-NPD, GC-μECD, HPLC-UV와 HPLC-FLD로 분석가능한 총 253종의 농약잔류량을 분석한 후 GC-MSD로 확인한 결과 총 14건의 건조농산물에서 잔류농약이 검출되어 24.1%의 검출률을 나타내었고, 이 중 건조 채소류의 검출률은 25.5%였다. 품목별 잔류농약의 검출률은 건조과채류, 간조엽채류, 건조엽경채류 순으로 높았으며, 특히 건조과채류 중 건조고추의 잔류농약 분포가 다양하고 검출빈도가 상당히 높았다. 건조농산물의 기준에 없는 12종의 잔류농약이 검출되었으며, 합성피레스로이드계, 유기염소계, 유기인계 순으로 검출빈도가 높았고, 특히 합성피레스로이드계 중 cypermethrin의 검출횟수가 가장 많았다. 또한 대상목적에 따라 분류하면, 살충제, 살균제, 제초제, 살선충제 순서로 검출건수가 많았다. 산지별로 보면, 국내산, 중국산, 북한산, 미국산, 베트남산의 순서로 잔류농약의 검출건수가 많았으며, 국내산은 과채류에서 수입산은 엽경채류에서 산류농약의 검출빈도사 높았다. The purpose of this study was to investigate 253 kinds of pesticide residues in 58 commercial dried agricultural products in Seoul. The determinations of the pesticide residues were performed using multiresidue methods and were carried out by a gas chromatography-nitrogen phosphorus detector (GC-NPD), an electron capture detector (GC-μECD), a mass spectrometry detector (GC-MSD) and high performance liquid chromatography-ultraviolet detector (HPLC-UV), and a fluorescence detector (HPLC-FLD). The pesticide residue detection rate in the commercial dried agricultural products was 24.1% (14 of 58 samples). Twelve pesticide residues without maximum residue limits (MRLs) were detected. In the vegetable groups, the frequency of pesticide residues was found to be in the increasing order of dried fruiting vegetables > dried leafy vegetables > dried stalk and stem vegetables. The pesticides used on dried red pepper in the dried fruiting vegetables were varied (7 kinds) and numerous (4 of 8 samples). The pesticide types detected in the commercial dried agricultural products were in the order of pyrethroid > organochloride > organophosphorus and insecticide > fungicide > herbicideㆍnematicide. The primary pyrethroid pesticide detected was cypermethrin. According to the producing areas of products, large numbers of pesticide residues were found in the order of Korea, China, North Korea, USA, and Vietnam.

        인삼 중 DDT(DDD 및 DDE) 분석법의 개발

        김성단(Sung-Dan Kim),조태희(Tae-Hee Cho),한은정(Eun-Jung Han),박성규(Seoung-Gyu Park),한창호(Chang-Ho Han),조한빈(Han-Bin Jo),최병현(Byung-Hyun Choi) 한국식품과학회 2008 한국식품과학회지 Vol.40 No.2

        GC-μECD 이용한 수삼, 건조인삼, 홍삼 중 DDT(o,p’-DDE, p,p’-DDE, o,p’-DDD, p,p’-DDD, o,p’-DDT, p,p’-DDT)의 효율적인 분석 방법을 살펴본 결과는 다음과 같다. 단순하며 소량의 용매를 사용하는 동시분석법을 이용하여 인삼으로부터 DDT(DDD 및 DDE포함)를 추출하고 헥산 및 6% 에테르 함유 헥산으로 SPE-Florisil(500 ㎎) 정제하는 것이 GC-μECD 크로마토그램에서 인삼고유성분과 DDT(DDD 및 DDE포함) 피크의 분리도와 회수율 측면에서 가장 효율적이었다. 또한 인삼 중 저농도(0.01-0.05 ㎎/㎏) DDT(DDD 및 DDE포함) 이성질체를 SPE-Florisil(500 mg) 정제 전 30% 황산 처리 후 원심분리로 인삼 고유성분을 제거하여 정확성을 높였다. 동시다성분법 추출 후 황산처리 및 SPE-Florisil(500 ㎎) 정제방법을 이용한 수삼, 건조 인삼분말, 홍삼분말에 DDT(DDD 및 DDE포함) 이성질체 표준용액을 0.01 ㎎/㎏ 농도가 되도록 첨가하여 실험한 회수율은 87.9-99.6%이었으며 표준편차는 0.9-5.9%였다. 또한 검출한계(Method Detection Limits)는 0.003-0.009 ㎎/㎏이었다. The MRLs (maximum residue limits) of DDT (DDD and DDE) in fresh ginseng, dried ginseng, and steamed red ginseng are set as low as 0.01 ㎎/㎏, 0.05 ㎎/㎏, and 0.05 ㎎/㎏, respectively. Therefore, this study was undertaken to develop a simple and highly sensitive analysis method, as well as to reduce interfering ginseng matrix peaks, for the determination of DDT isomers (o,p’-DDE, p,p’-DDE, o,p’-DDD, p,p’-DDD, o,p’-DDT, and p,p’-DDT) in fresh ginseng, dried ginseng, and steamed red ginseng at the 0.01 ㎎/㎏ level. The method used acetonitrile extraction according to simultaneous analysis, followed by normal-phase Florisil solid-phase extraction column clean-up. The purification method entailed the following steps: (1) dissolve the concentrated sample extract in 7 ㎖ hexane; (2) add 3 ㎖ of H₂SO₄; (3) vigorously shake on a vortex mixer; (4) cetrifuge at 2000 rpm for 5 min; (5) transfer 3.5 ㎖ of the supernatant to the Florisil-SPE (500 ㎎/6 ㎖); and (6) elute the SPE column with 1.5 ㎖ of hexane and 10 ㎖ of ether/hexane (6:94). The determination of DDT isomers was carried out by a gas chromatography-electron capture detector (GC-μECD). The hexane and ether/hexane (6:94) eluate significantly removed chromatographic interferences, and the addition of 30% H₂SO₄ to the acetonitrile extract effectively reduced many interfering ginseng matrix peaks, to allow for the determination of the DDT isomers at the 0.01 ㎎/㎏ level. The recoveries of the 6 fortified (most at 0.01 ㎎/㎏) DDT isomers from fresh ginseng, dried ginseng, and steamed red ginseng ranged from 87.9 to 99.6%. The MDLs (method detection limits) ranged from 0.003 to 0.009 ㎎/㎏. Finally, the application of this method for the determination of DDT isomers is sensitive, rapid, simple, and inexpensive.
